    or you could attach a failure handler

    How does vertx 
    HTTPServerResponse#setChunked
    interact with HTTP/2? Docs said it does nothing, and I'm assuming because HTTP/2 is smarter, that it's as if 
    setChunked is true?

    I wish this channel has more members. I want to get started with backend programming, but I'm not sure if starting my journey with Vertx is a good plan. I like it's programming model, but is it widely used?
  • a
    @manlan it is not widely used - it is a great library though

    I am always monitoring this channel for questions

    there is also the google group or the gitter channel if you need to reach the authors

    how does one implement a streaming upload handler in VertX? if i'm uploading a 10GB file, i don't want it to sit inside an in-memory buffer I've started messing around with custom handlers, but not sure how to access the stream
    Copy code
    class LulaUploadHandler : Handler<RoutingContext> {
			override fun handle(ctx: RoutingContext) {
				try {
					val request = ctx.request()
					request.streamPriorityHandler {
						<http://log.info|log.info>("blah")
					}

					<http://log.info|log.info>(request.bytesRead().toString())



				} catch (e: Exception) {
					log.error(e.message ?: "", e)
				}
				ctx.response().end("completed")
			}
		}
		<http://router.post|router.post>("/leupload").handler(LulaUploadHandler())

    Hi guys do you know how enable the Vertx sync? I read the documentation and the application should start with Quasar as java agent… ? other ideas / direction that I could follow?
  • j
    I'm trying to update Vert.x 3.8.5 code to 4.0 beta 3... isn't Kotlins String extension still supporting toLong(), toInt() ...?

    I wish the Vertx team uses Slack than Gitter/Discord 😐 Slack's lot more intuitive and following up on threads is way easier here.
  • a
    Yeah gitter ui sucks

    Indeed. Just wondering, does anyone know why? They've been using Gitter since I can remember though

    I think its easier when you have the whole world posting on it compared to a small team
  • d
    Not sure if some of their points are still valid, but I get the GitHub integration. Oh well, we're here though 😛

    That 70 billion events per day capacity was made possible by Kotlin with Vert.x 🙂

    I'm looking for some examples of writing unit tests for vertx coroutines. The documentation from https://vertx.io/docs/vertx-lang-kotlin-coroutines/kotlin/ doesn't have any sample unit tests. Even the sample project from https://github.com/vert-x3/vertx-examples/tree/4.x/kotlin-examples doesn't have a unit test.

    This channel doesnt get used all that much
  • a
    Also get used to it - vertx and kotlin is a niche stack you have to pave your own way

    I have been using vertx for many years and think it is one of the greatest libraries for networked applications. I created a course that is live on udemy to help devs get into backend development with vert.x or anyone trying to level up in general. The course uses kotlin as its primary language too I hope many of you here would find it useful and interesting. It contains 5.5 hours of video content talking about concepts and code both https://www.udemy.com/course/backend-development-with-vertx/?referralCode=063C2D57CCB957C5088C
